Developing and regenerating glands were labeled with bromodeoxyuridine (BrdU). To cause gland regeneration, the glands were injured by duct obstruction. BrdU LRCs were observed in all the parenchymal structures except for the acinus of the glands labeled during regeneration. Among these LRCs, a few, but not many, expressed neither keratin18 (K18; an acinar\/duct cell marker) nor \u03b1-smooth muscle actin (\u03b1SMA; a myoepithelial cell marker), and thus were putative stem cells. These (K18 and \u03b1SMA)\n                    <jats:sup>neg<\/jats:sup>\n                    LRCs were invariably observed in the intercalated duct and the excretory duct. In the intercalated duct, they were at the proximal end bordering the acinus (the neck of the intercalated duct). Next, to test the above identification, gland extirpation experiments were performed. LRCs were established by labeling developing glands with iododeoxyuridine (IdU) in place of BrdU. Removal of one submandibular gland forced the IdU-LRCs in the remaining gland to divide. They were labeled with chlorodeoxyuridine (CldU). The (K18 and \u03b1SMA)\n                    <jats:sup>neg<\/jats:sup>\n                    LRCs in the neck of the intercalated duct and in the excretory duct did not change in number or in IdU label. The CldU label appeared in these cells and then disappeared. These results indicate that the (K18and \u03b1SMA)\n                    <jats:sup>neg<\/jats:sup>\n                    LRCs have divided asymmetrically and are thus considered salivary gland stem
